Scott Aaronson is a computer scientist at the University of Texas in Austin, whose research mainly focuses on quantum computing and complexity theory. He’s at least very adjacent to the Rationalist/LessWrong community. After some comments on his blog and then coversations with Jan Leike, he’s decided work for one year on AI safety at OpenAI.
To me this is a reasonable update that people who are sympathetic to AI safety can be convinced to actually do direct work.
Aaronson might be one of the easier people to induce to do AI safety work, but I imagine there are also other people who are worth talking to about doing direct work on AI safety.
